Say to the girl:' don't be sad, brother, I'm just saying.' How does this sentence become a transitive sentence?

The girl told her brother not to be sad, she was just talking casually. It seems that this explanation is the best, because the subject is a girl, not a personal pronoun, but a noun. If it is changed into a transitive sentence, it will change the personal pronoun and add some verbs or prepositions to modify the object. This is almost the format, just set it slowly. For example, the teacher said to Badoni, "I know you screwed up. Blow it again! " The teacher told Badoni that he knew it was Badoni and asked Badoni to play it again.
